Heavy rain will not flood the car. Here is the relevant information: 1. Waterlogged sections: If the engine stalls during vehicle wading, immediately turn on the hazard lights, shut off the engine, and turn off the ignition. Never attempt to restart the engine, as doing so can easily cause fatal damage to the engine and will not be covered by insurance. 2. When stationary: If the vehicle is submerged while parked in a basement or parking lot, lock the vehicle and do not attempt to start the engine. Try to seal the vehicle as much as possible and do not remain inside the flooded car. After the vehicle is submerged and the engine stalls, the interior becomes the most unsafe. If the water level rises rapidly and the doors cannot be opened or closed, passengers may become trapped inside and suffocate after the vehicle loses power.

I've experienced the issue of water leakage in my car during heavy rain, where rainwater seeped in through gaps in the door seals, causing troublesome water accumulation inside the vehicle. The main causes are aging seals or door deformation, and neglecting regular checks makes this problem more likely to occur. Clogged drainage holes are also problematic; located under the car and beneath the hood, they can cause water to pool during heavy rain, leading to corrosion of the chassis or electronic components over time. Now, I regularly inspect the condition of the seals and use water during car washes to test for leaks, promptly replacing any damaged parts. Before the rainy season, I ensure the window seals are intact, park on higher ground to avoid flooding, and use accessories like rain guards for added protection. However, the key is maintaining the sealing system to prevent water infiltration, which can compromise driving safety. These experiences have taught me that prevention is far more important than repairs.

As someone who deals with many vehicle issues, I know heavy rain can cause water intrusion, especially when seals fail. Aging and deformed door rubber seals, clogged sunroof drainage tubes, or cracked body welds can all allow rainwater to seep inside. The consequences go beyond damp interiors—it may short-circuit lighting or the starting system. I recommend checking the sealing during annual maintenance by pressing the seals to test their elasticity. Replacing worn parts is inexpensive. Keeping drainage channels clear is crucial; removing accumulated dust and fallen leaves is essential. Always close windows and doors tightly when parked, and adding rain guards can enhance protection. Water intrusion risks include mold and electrical failures. Early repairs prevent greater losses, keeping the vehicle dry and safe. Regular maintenance is the best way to avoid these problems.

During heavy rain, water may enter the car. I always make sure to close all windows and doors. Intact seals can prevent rain, but if they are aged or cracked, they need replacement. Try a simple method: before it rains, splash water near the windows to check for leaks and repair them promptly. Ensure drainage holes are not blocked to prevent water accumulation and seepage. Choose higher ground to park and avoid puddles. Keeping the interior dry is crucial to prevent electronic damage. Also, check the seals on the sunroof and trunk.

Water entering a vehicle not only wets the seats but also poses a greater danger of short-circuiting the electrical system. In practice, I emphasize the risks of heavy rain: rainwater can corrode wiring harnesses or cause malfunctions, making driving unsafe. Regularly inspect the seals on doors and sunroofs to avoid gaps. Keeping the drainage system clear is essential; remove mud and standing water. When parking, avoid low-lying areas and install waterproof films to block rain. Before the rainy season arrives, conduct a comprehensive inspection and replace damaged parts to prevent water ingress accidents. Protecting your car extends its lifespan, with safety as the top priority.
